a umen.

To all 107mm it may concern Be it known that I, ARTHUR H. ADAMS, acitizen of the United States, formerly of Spar'kill, in the county ofRockland and State of New York, and now residing n Brussels, Belgium,have invented a certain new and useful Improvementin Semi-AutomaticWinding-Machines, of which the following is a full, clear, concise, andexact description.

This invention relates to winding machines and particularly to machinesadapted for winding insulated wire in uniform layers on spools.

The general object of my invention is to provide a new and improvedwinding machine by which the spools may be quickly and satisfactorilywound, and which can be adjusted for the winding of spools of dif ferentlengths with different sizes of wire.

My invention will be understood from the following description taken inconnection with the accompanying drawings in which- Figure l is aperspective view of a machine having my invention embodied therein, thetable which covers certain of the parts being removed; Fig. 2 is a planview of the machine; Fig. 3 is a sectional elevation on the line 3-3,Fig. 2; Fig. i is a front elevation, certain parts being broken away;Fig. 5 is a detail plan view showing the scale for indicating the sizeof wire for which the machine is set; Fig. 6 is a detail plan view ofthe circuit changing device; and Fig. 7 is a diagram of the circuitthrough which the magnetic clutch device is controlled.

Referring to the drawings, the major part of the mechanism of the deviceis mounted on a frame 10 having hollow, spacing pieces 11, and fixed tothe under side of a table 12, by bolts like 6, so that the moving partsare below table 12 leaving the upper side of the table free and clear.-There is a track or runway 13, head block b and tail block 0; on track13 there runs.a front carriage 14, like a tool rest, carrying thegrooved guide 7 for guiding the insulated wire in helical convolutionsonto the spool s which is to be filled with wire. Spool s has flanges f,one at each end; these are usually circular in outline as shown. Thereis a back carriage 15 traveling on a track 16; the two carriages l4 and15 are mechanically united by a lever Specification of Letters Patent.

1T oscillating on a pivot at 18; one end of lever 17 is pivoted ,to backcarriage 15 at 19,

the opposite end of lever 17 is pivoted to the front carriage 14 at 20.The front carriage 14: travels in the reverse direction with respect tothe movement of the back carriage 15. The motor m which drives oroperates the machine as shown, is an electric motor and it is connecteddirectly to the arbor 21 by means of an insulating coupling 22. Thearbor 21 supports the spool s, to be wound with wire. There is a handwheel 24 on shaft or arbor 21 operated as a hand brake stopping themachine when the requisite number of turns have been put upon the spoolbeing wound.

The main shaft or arbor 21 has fixed upon it a worm 25 gearing with aworm wheel 26, fixed on a shaft 27; upon the opposite end of shaft 27 isa gear wheel 28. This wheel 28 meshes with wheel 29 upon a short shaft30 bearing a worm 31 meshing with a gear wheel on a short vertical shaft33 on which is fixed pulley p. Passing around pulley 7) is a drivingbelt 9 made of some fabric. like woven linen, having two parallelsections 34 and 35, moving in respec tively opposite directions. Thisbelt 9 passes around idle pulley 9 located on a movable support 36adjustable to and fro with respect to pulley p by a screw operated by athumb piece 37, by which meansbelt 9 may be tightened. The loose pulleys38 and 39 are used to adjust the belt and maintain sections 34 and insubstantially parallel relation. Two double coil electromagnets $0 and41 moving with the rear carriage 15 have a common armature 42, pivotedat 43; above armature 42 is a yieldin spring-pressed retaining device 44to ho ld the armature in either of its two'extreme positions. 'Theretaining device 44 is carried in a frame 43 forming part of carriage15. The belt passes on opposite sides of armature 42, the two sectionsmoving in opposite directions, as already explained, and when thearmature 42 is attracted to one side or the other, the 'belt section 34or is gripped between a magnet pole and the armature, and the carriage15 is carried along in one direction according as the belt section 34 or35 is gripped. The electrical connections are shown in Fig. 7; it willbe noticed that circuit is normally closed S a hard rubber shoe 46 andas shown in Figs. 1 and 2, shoe 46 is located in line of movementosition to engage flanges f.

Assumin i, the carriage is started 1 a the is the spool, the travel isfrom ti l nd flange f laying. the

of the wir upon the spool as it con-v toward the opposite end of thecoil. 14. ume the belt locked against the back magnet core, when thefront carriage 14 reaches the right-hand end of the spool shoe 46 willstrike right-hand spool flange'f and contact 49will beopened, breakingcircuit through coils of 41, the armature 42 is drawn over to the frontmagnet coil 40- clutching carriage '14 to section 35 of the .belt, thusreversing the movement of carriage l4 and the operation is repeated,spool shoe 46 next striking the left-hand spool flange )3, and so on, insuccession until the operator stops the machine.

The circuit-closing switch shown in Fig. 6 has two 'stifi' springs 47and 48, and two light spring contacts 49 and 50; there are two fixedcontacts 51 and 52; each has a hard rubber contact" point 80 projectingthrough a perforation in the contact 49 or 50, and engaging contact '47or 48 so that when contact 45 is moved in one direction, contact 45separates from contact 49,'and when moved in the other direction,contact 45'separates from contact 50. The shoe 46 is shaped for use withround heads or flanges f. In case square heads or flanges are employedonthe spools tobe' wound, useis made of the round thumb nuts 53 and 54on the fixed screw rod 55. The space between the inside facesof nuts 53and 54 is made equal to the winding space upon the coil. Thecontactsprings shown in Fig. 6 are carriedoupon an adjustable L-shapedbracket 56,

"pivoted at. 57 to an upright 58 of the frame.

A, locking screw 59 projecting through a slot 60 ,inthe bracket 56 intothe upright 58 serves'to hold the bracket 56 and the contact springscarried thereby, in any desired position. By loosening the locking screw59, the shoe/l6 may be positioned to engage the heads of any siz'e'ofspool for which the machine is supposed to operate, or'in case square orirregular shape headed spools are to be wound, lowered to engage thenuts 53 and 54. The shoe 46 engaging the nuts 53 and 54 causes thereversals in the movement of,"the ,winding mechanism in exactly the samemanner as when the shoe 46 engages the sp'ool heads.

The guide rollerg is suspended from a guide lever 81 by a connecting arm82. The arm 82 is pivoted to the lever 81 on a .kn urledheaded tensionadjusting screw83.

In the various drawings-the guide 9 is shown in the position assumedwhen a spool is being'wound, but it may be raised and 21 front of thespool n 18 completed he spool from and the other in the non-operativeposition.

The pawl 86 is normally held in engaging position by a spring 88 locatedbetween the guide lever 81 and the latching lever 85. By pressingtheouter ends of levers 81 and 85 together, against the tension of spring88, the .pawl. 86 may be withdrawn from the notch in disk 87 and theguide 9 moved about the pivot 84 to the other position.

In adjusting the speed of front carriage 14, and to determine the properpitch at which various kinds and sizes of wire are'to be wound, theoperator measures with a micrometer the outside diameter of the wire,and then directs attentionto dial or indicator a graduated tothousandths of an inch. The arm 17, uniting the two carriages 14 and 15is on a pivot 18; the arm 17 is slotted and pivot 18 extends through theslot. Pivot 18 is supported on a mit62,--slidable in a slot 63 in thefixed bed 64. Nut 62 travels on screw 65, said screw terminating in theknurled circular thumb piece 66. On the same screw 65 is a worm 67meshing .with a worm wheel 68 on which is fixed a plate havingthereongraduated scales 69 and 7-3. The zero. point for scale 69 is shown at75, and the zero point for scale 73 at 7 6. The

gears 28 and 29 are of different sizes and are I interchangeable on theshafts 27 and 30. When said gears are arranged as shown, one of thescales 69 or 73 is used; and when said gears are interchanged the otherof said scales is employed. When the gears 28 and 29 are arranged on theshafts 27 and 30 as shown, for example, if the machine is to be settowind wire having a diameter .0035 of an inch, the thumb piece 66 isturned until the figures .0035 on the scale 69 are opposite the zeropoint 75. And if the diameter of the wirehad been .009, the gears 28 and29 would have been interchanged on the shafts 27 and 30, and the frontpiece 66 ,would have been turned until the figure .009 on the scale 73was opposite the zero point 76; it being understood that the nut 62 isalways in the same position when the gears 28 and29 are changed. Withthe'arrangement just described, it is obvious that indicates the numberof turns put on any spool.
